DesignBuilder（version 6.1.5.001）とR（version 4.0.4）を使ってASHRAE Standard 140の単室テストを実施する。
IDE（統合開発環境）は、IDFはVisual Studio Code（version 1.54）、RはRstudio（version 1.4.1106）を使用。
1 DesignBuilderによるCase600モデルの作成
1.1 新しいプロジェクトを作成
1.2 Locationの定義
1.3 新しいBuildingの作成
1.4 新しいBlockの作成
1.5 Activityの入力
1.6 Constructionの入力
1.7 南面以外のOpeningの削除
1.8 南面の窓面の入力
1.9 Ground floorをExternal floorに変更
1.10 HVACの入力
1.11 IDFファイルのExport
1.12 IDFファイルのバージョンアップデート
DesignBuilderから出力したIDFファイルのEnergyPlusバージョンは8.9.0のため、最新バージョンにアップデートする。 EnergyPlusに付属のIDFVersionUpdaterを使用することで簡単にアップデートが可能。
（Appの場所は“EnergyPlus-9-4-0/PreProcess/IDFVersionUpdater”）
1.13 手作業によるIDFファイルの修正
床面積と容積が合っていないため修正。おそらく壁の厚さを考慮しているため。
